Britain’s biggest ever bottle of English sparkling wine, produced by award winning, Kent-based winery Chapel Down, has been signed by four leading contemporary British artists and will be sold at Christie’s ‘Out of the Ordinary’ auction on 3 September 2014 to raise funds for Turner Contemporary’s Catalyst Endowment campaign.

The unique bottle, produced to celebrate Turner Contemporary’s one millionth visitor in August 2013, is an expertly made 15-litre Nebuchadnezzar of Chapel Down’s trophy-winning Blanc de Blancs 2007 sparkling wine.

Weighing 26kg, it is the equivalent of 10 magnums, or 120 glasses, and contains around 60 million bubbles – one for every person in the UK.

The bottle has been signed by four leading British artists, including Damien Hirst, Tracey Emin, Antony Gormley and Edmund de Waal.

Each artist has accompanied their signature by a sketch which pays tribute to their career and practice, including a shark by Damien Hirst, a self-portrait by Tracey Emin, an outline of a male figure by Antony Gormley, and a list of previous installations by Edmund de Waal.

The signed Nebuchadnezzar forms part of Christie’s second annual ‘Out of the Ordinary’ sale, a tightly curated sale offering a unique opportunity to acquire something a little different from Christie’s South Kensington. Each lot has been selected as either visually striking or with an intriguing story to tell, many of which have never before been seen at auction.

From 5 August 2014, the Nebuchadnezzar will go on display at Christie’s South Kensington with an estimated price of £10,000-£15,000. All proceeds raised from the sale will significantly contribute towards Turner Contemporary’s Catalyst Endowment Fund, which must reach a £1 million target by March 2015.

As part of a scheme to make arts organisations more sustainable, every £1 raised will be matched by £1 funding from the Catalyst Endowment Fund, which is supported by Arts Council England and DCMS. These funds will mean that Turner Contemporary can continue to make world-class art accessible to everyone, growing the learning and outreach programmes and making an even greater impact on Margate and Kent’s future.
